Development of Material Evaluation Techniques for Advanced and Innovative Batteries (Phase 2)

Project overview

Project period: FY2018 to FY2022, FY2019 budget: JPY 1.88 billion

The project seeks to promote collaborations between automobile, storage battery, and material manufacturers and universities/public research institutes in order to establish basic technologies for resolving challenging issues common to all-solid-state lithium-ion batteries. At the same time, prototype cells are also being used to develop the technology necessary to evaluate the characteristics of new materials and their suitability for mass production and installation on electric vehicles (EVs). In addition, the project aims to develop safety and durability test evaluation methods while keeping in mind an international standardization process led by Japan. In parallel with the above research and development, this project also involves the consideration of future societal system designs and scenarios to accommodate the large-scale dissemination of EVs.
